              As part of a project sponsored by FRA, TTCI developed and analyzed a concept for the Office Safety Checker (OSC) component of the Moving Block Office (MBO), a segment of a moving block train control system concept. The OSC component performs a safety validation of MBO safety-critical functions and certain Positive Train Control Back Office Server (PTC-BOS) safety-critical functions. It also leverages on the Quasi-Moving Block (QMB) Operational Concept and the Overlay Positive Train Control (O-PTC) concepts.
